This is a wall-sleeve heat pump and backup-heat system for hotel rooms, apartments, or additions where central ductwork isn't available. It's built for property managers and coastal-property owners who need self-contained, per-room heating and cooling with added corrosion protection near saltwater or seacoast air.
The PTH124J50CXXX is a 265V packaged terminal heat pump (PTHP) with 5.0 kW electric backup heat, engineered for hospitality corridors, additions, and coastal properties where per-room climate control replaces central ductwork. The "C" feature code identifies this unit as Seacoast Protected, meaning the coil and cabinet components carry enhanced corrosion protection for high-salinity air environments. This unit is built to meet or exceed ASHRAE 90.1 efficiency standards. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
- Wall sleeve opening required: Standard 42 in wide x 16-1/16 in high (industry-standard PTAC/PTHP sleeve size).
- Voltage: 265V commercial. Operating range 239V minimum to 292V maximum.
- Electric heat: 5.0 kW single-stage, drawing 19.2 total amps / 5,070 watts at 265V (MCA 23.9A, MOP 25A).
- Power cord: 7-30P NEMA plug configuration.
- Wall Sleeve is NOT included. Exterior Architectural Grille is NOT included. Both are sold separately.
- Not compatible with 115V circuits. Not compatible with 230/208V circuits — for that voltage class, see the sibling chassis PTH123J.
- 265V installs require an Amana-brand sub-base (PTSB4**E series) or the PTPWHWK4 hard-wire kit with PSHW04A disconnect switch. Neither is included with this chassis.
- Not a drop-in replacement for non-standard or custom sleeve openings.
The technical friction on a 265V seacoast job like this one is twofold: matching the 7-30P plug to the correct NEMA receptacle in the sub-base, and getting the sleeve pitch right before the drywall closes up. Field crews sometimes assume all PTAC/PTHP sleeves are level — they are not. Pitch the sleeve 1/4 bubble toward the outside wall (per the framing diagram) so condensate runs out through the drain path instead of pooling against the interior wall cavity. Verify that pitch with a Torpedo Level on the sleeve rail before securing it, and cross-check the receptacle against a NEMA Receptacle Chart to confirm the 7-30P plug lines up with the sub-base you're installing — not the 230/208V sub-base meant for the sibling chassis. On seacoast properties, also confirm the cartridge-style time-delay fuses are factory-installed before energizing the circuit; that's a code-relevant step under commercial NEC receptacle requirements for 265V equipment, and it's standard practice for any property management team documenting a unit turnover.
Key Benefits
- Heat pump operation delivers 11,500 BTU/h of heating from the compressor before backup heat engages, reducing electric-heat runtime compared to heat-strip-only PTAC units.
- 5.0 kW backup heat strip raises total heating output to 17,100 BTU/h at 265V for cold-snap coverage.
- Dehumidification rate of 1.7 pints/hour helps manage humidity load in guest rooms without oversizing the compressor.
- Fresh air ventilation adjustable from 65-95 CFM supports make-up air needs in occupied hospitality spaces.
- Seacoast corrosion protection (feature code C) extends service life in coastal and high-salinity environments.
- EER of 11.3 and COP of 3.3 provide a documented efficiency baseline for cooling and heat-pump-mode comparisons.

Frequently Asked Questions
Is the wall sleeve included with this unit?
No. The wall sleeve is sold separately. This chassis fits the industry-standard 42 in wide x 16-1/16 in high sleeve opening (e.g., WS900E, WS900QW, or the WS900SC seacoast-protected sleeve). The exterior architectural grille is also sold separately.
What breaker size and plug type does this unit require?
This 265V configuration with the 5.0 kW electric heat installed has a Minimum Circuit Ampacity (MCA) of 23.9 amps and a Maximum Overcurrent Protection (MOP) of 25 amps. It ships with a 7-30P power cord. It requires cartridge-style, factory-installed time-delay fuses for 265V service.
Can this be hardwired for 265V commercial applications?
Yes, but only with the correct accessories. All 265V Amana models must use an Amana-brand sub-base (PTSB4**E series) or the PTPWHWK4 hard-wire kit paired with the PSHW04A disconnect switch. These are sold separately and are not included with the chassis.
Does this require a licensed electrician or HVAC professional to install and keep the warranty valid?
The 265V voltage class and hardwire/sub-base requirements mean this installation involves dedicated commercial electrical work. Refer to the Resources (System Manuals and Warranty) Tab above for the manufacturer's specific installation and warranty-validity requirements.
Will this fit a standard 42-inch by 16-inch wall sleeve opening?
Yes. This chassis is designed for the industry-standard 42 in x 16-1/16 in wall sleeve opening. It is not a drop-in fit for non-standard or custom-sized openings.
